Another important 'object of thistonprovidefa structure'whicl'isso desi a' person v forki'gA alone may'connect/the tractor una' to the mad 'without neeaingtean jud during'the'operation. Another important object of this invention is to provideapwr transmitting unit such that the tractr'nt inay be connected to the load and then, Vafter this 14ov for .assistanceand without danger of being in' l.

has been done, the connection oi the power takeoi between the power generating unit and the power utilizing unit may be made simply and easily, and such further objects, advantages, and i* capabilities as will hereafter appear and as Vare inherent in the construction disclosed. herein.

This invention further resides in the combination, construction, and arrangement of parts illustrated in the accompanying drawing and, while what has been shown therein is regarded asl-thejpreferredembodiment of this invention, itg i s desired that thesame be understood as illustrative onlyand notfbe interpreted in-a' limiting Sensei' In thedrawing annexed heretovand forming Fig. 1 Arepresents'aifragmentary s ide'elevation .of a .structure embodying the present invention;

Thus, it will be seen that, when the ends of parts I and 2 are inserted into the member 3, they may encircle the reduced ends 5 and B of the block 4.

From the foregoing it will be seen that, wheni If it is desired to drive a rotary mechanisml forming a part of the load, for example, the mechanism of a corn picker orother machine, the tractor is first hitched to the load and then the unit 3 is applied to the unit 2, with which theV corn picker has been supplied. The two are shoved together until the forward end of the unit 2 abuts against or substantially against the block 4. ,The forward end of the unit 3 is then raised and brought into alignment with the unit I` with which the tractor has been equipped. When the two have been brought into alignment, then the central unit, 3, 4, 5, 6 is moved -forwardly until the rear end of theunit l abuts against or substantially against the block. 4. When this is done, the plunger f1 enters into the opening I provided for this plunger and fastens the two'together.' This is done by moving the central unit forwardly without moving either tractor or load. When the plunger 1 snaps into the opening l0 there is no danger of disconnection at any point in this power -take-oifv unit. Furthermorethere is no projection on the outer surface of this unit which couldresult in the operators clothing getting caught and-causing injury to him.

From the foregoing it willbe seen how simple this construction is, how easily it can bel fabricated, how easilythe power take-off unit can be connected between the traction'vunit and the load, and how well'adapted this device is to, carry vout allof the objectsstated above.
